oxidation-reduction

 [ok″sĭ-da´shun-re-duk´shun]
the chemical reaction whereby electrons are removed (oxidation) from atoms of the substance being oxidized and transferred to those being reduced (reduction).

ox·i·da·tion-re·duc·tion

(ok'si-dā'shŭn-rē-dŭk'shŭn),
Any chemical oxidation or reduction reaction, which must, in toto, comprise both oxidation and reduction; the basis for calling all oxidative enzymes (formerly oxidases) oxidoreductases. Often shortened to "redox."
